   Summary

   Red didn't care what people thought or did. Why should he?

   He also shouldn't care if Hearts, Underlust Sans, didn't flirt with him. Hearts flirted with everyone with that -adorable- stutter of his. Flash a smile, wink and give a flirty comment. He did this to everyone, everyone but Red.
